KETTLE :FURNAGE j Application led May 18, 1925. Serial No. 30,994.

To all 'whom t may concern:

Be it known that I, Nummer A. Lan, a citizen of the United States of America, residing at Ector, in the county of Fannin and State of Texas, have invented certain new and useful Improvements in Kettle Furnaces, of which the following is a specifi-v cation.

This invent-ion relates to new and useful improvements in kettle furnaces.

The object of the invention is to provide a kettle furnace which may be made in a simple and economical manner.

A particular object is to provide an adjustable frame whereby old wash tubs may be utilized to form the casing or jacket.

A further object is to provide a furnace which may be mounted to revolve so as to get. a better draft.; or which may be immovably supported.

A construction designed to carry out the invention will be hereinafter described together with other features of the invention.

The invention will be more readily understood from a reading of the following specifiw cat-.ion and by reference to the accompanying drawings, in which an example of the invention is shown, and wherein:

Fig. 1 is a vertical partial sectional view of a. furnace constructed in accordance with my invention,

Fig. 2 is a horizontal cross-sectional view taken on the line 2-2 of Fig. 1, and

Fig. 3 is an enlarged sectional view showing the adjustable frame connection.

In the drawings the numeral 1()` designates a circular dished disk forming the bottom of the furnace. The disk has a depending annular apron 11 provided with an outwardly directed horizontal flange 12 at its lower edge. Contiguous to the inner wall of the apron the disk is formed with a plurality of slots 13.

Vertical frame bars 14 extend through the slots and have inturned feet 15 at their lower ends to support the furnace on the ground. At their upper ends the bars are offset inwardly toform shoulders 16 for receiving a top band 17 which is riveted to said bars. The band is less in diameter than the apron 11.

The bars 14 have spaced apertures 18 for receiving stove bolts 19 having their heads Tccuntersunk inthe apron. By adjusting the bolts in the apertures the elevation of the band from the flange 12 may be varied. The frame formed by the parts 11, 12, 14 and 17 is surrounded by a casing or acketl 20, preferably of sheet metal. One of the particular features of the invention is the utilization of old sheet metal wash tubs for the jacket. Such tubs usually have good side walls and a worn out bottom. The bottom is cut out of the tub which is inverted and slipped over the frame with its bead 21 resting on the flange v12 and fitting snugly around the apron.

A. door 22 of any suitable character may be mounted on the jacket diamet-rically opposite a flue collar 213 to which a pipe 24C is attached. Below the collar a horizontal baffle plate 25 is fastened in the jacket. The disk is formed with slots 26 constituting a grate and affording a draft. If it is desired to revolve the furnace so that the door 22 may face the wind and afford a draft when opened, the disk 10 may be formed with a depending central step 27 for receiving the upper end of a metal pin 28 driven intothe ground as -is shown in Fig. 1.

Various changes in the size and shape of the different parts, as well as modifications and alterations may be made within the scope of the appended claims.

What I claim is:

1. In a kettle furnace, a circular disk, a supporting flange surrounding the disk, frame bars extending through the disk within the flange, a sheet metal casing sur rounding the disk and resting upon the flange, and means for supporting the disk and flange abo-ve the ground.

2. In a kettle furnace, a circular disk, a supporting flange surrounding the disk, a supporting frame structure adjustable vert-ically with relation to the disk, and a jacket surrounding said frame structure and resting upon said flange.

3. In a kettle furnace, a` circular disk having a surrounding flange, vertical frame bars extending through said disk, a band connecting said bars, and a jacket surrounding the disk and bars and resting upon the flange.

4. In a kettle furnace, a circular disk having a surrounding flange, vertical frame bars extending through said disk, a. band connecting said bars, and a jacket surrounding the disk and bars and resting upon the flange, rthe bars being adjustable 'vertically of the disk. 4

5. In a kettle furnace, a circular disk having 'a 'surrounding flange, `Vertical frame bars extending through said fdisk, 1aband connecting said bars, a jacket surrounding the. disk and bars and resting upon `theflange, and means for adjustab-ly fastening the bars to the disk.

6. In ar kettle furnace, a circular disk 'having a depending apron provided'with an outwardlyv directed flange, frame. hars extending through the disk, bolts securing the bars 'to the apron, a band fastened to the upper ends of the hars, and a jacket surrounding the bars and apron'and resting on the flange.

7. In a kettle furnace, a circular disk having adepending apron provided with an outwardly directed flange, frame bars extending through the disk, bolts securing` the bars to the apron, a band fastened to the upper ends of the bars, and a jacket surrounding the Ivbars and apron and resting on the flange, said bars having supporting feet at their lower ends.

In testimony whereof I affix niy signature.

WILLIAM A. LEE.
